Fast and robust computation of low-thrust orbit-raising trajectories
(American Institute of Aeronautics and Astronautics, Inc. Read More: https://arc.aiaa.org/doi/10.2514/1.G003319, 2018-09)This paper presents a new dynamic model of a thrusting spacecraft, and the model is used for computing low-thrust orbit-raising trajectories to the geosynchronous equatorial orbit. Low-thrust orbit raising is a challenging ... -
Fast effective deterministic primality test using CUDA/GPGPU
(Council for Innovative Research, 2015-01-04)There are great interests in understanding the manner by which the prime numbers are distributed throughout the integers. Prime numbers are being used in secret codes for more than 60 years now. Computer security authorities ... -
A fast flexible simulation platform for multi-core systems
(Wichita State University, 2012-05)As the popularity and demand grow, high-performance systems are adopting more processing cores. IBM Roadrunner, a petascale supercomputer, has 130K+ cores. No wonder, designing and/or analyzing such a gigantic system is ... -
Fast l(1)-norm nearest neighbor search using a simple variant of randomized partition tree
(Elsevier B.V., 2015-08-08)For big data applications, randomized partition trees have recently been shown to be very effective in answering high dimensional nearest neighbor search queries with provable guarantee, when distances are measured using ... -
Fatigue behavior of plasma spray coatings on polymer matrix composite materials
(Wichita State University, 2008-12)The majority of coated structural components are subjected to fluctuating internal and/or applied stress because of oscillating mechanical loads. The fatigue behavior of coatings and the overall cyclic failure response of ... -
Fatigue characterization of plasma spray coated composites
(American Society of Mechanical Engineers, 2012)In this work we study the fatigue behavior of plasma sprayed metallic coatings on graphite reinforced polymer matrix composites. In the absence of any standards for testing of coatings, the ASTM standard for composites was ... -
Fatigue life determination of a damage-tolerant composite airframe
(Wichita State University, 2008-12)The methodology proposed in this research extends the current full-scale test approach based on the life factor and the load enhancement factor, and provides information necessary to define inspection intervals for composite ... -
Fatigue life estimation of notched aluminum sheet specimens subjected to periodic tensile overloads
(Wichita State University, 2010-08)Structural elements are subjected to variable amplitude/spectrum fatigue loading where tensile overloads and compressive underloads may occur randomly. Depending on the magnitude of these loads, localized plastic deformation ... -
